Patented July 28, 1953 UNITED STATES PATENT @FFHQE DIAMIN E -BIS -ACETAMIDES Arthur L. Jacoby, deceased, late of Western Springs, Ill., by Ruth P.

Claims.

This invention relates to high molecular weight N,N-disubstituted diamides of complex dibasic acids, and more specifically to new chemical compounds of that character having the general formula:

H H H H wherein Y and Z have the foregoing significance, X is the residue of an organic polyamine, e. e., phenylene, alkylene, and polyalkylene polyamino, and y is zero or one.

The compounds of this invention, when conforming to certain structural limitations, as more fully set forth hereinafter, are greases or waxes of varying degrees of hardness and are valuable as substitutes for natural waxes, as constituents of coating compositions, as corrosion inhibitors, as defoamers, and as intermediates for the preparation of other valuable compounds.

An example of a compound represented by the above formula is N,N'-diethylenetriaminobis-N octadecylacetamide, obtained by the reaction of two mols of N-octadecylchloroacetamide and one of diethylenetriamine according to the following equation:

of the organic polyamine, the residue of which is represented by X in the formula, may be varied considerably. Thus, coupling has been efiected by means of such amines as hydrazine, piper- 5 azine, the polyalkylenepolyamines, alkylenediamines, and the phenylenediamines, yielding eflicient products in every case. Obviously, inthe case Where hydrazine is the coupling agent,'the (X) of the general formula will be absent, 1. e.,

y will be zero.

The simplest method of manufacturing the materials of this invention involves the initial formation of the N-alkylated amide of th halogeno-acid by merely heating the desired amine 13 with the halogeno-acid (or corresponding acid halide), and the subsequent coupling of the product by introducing the polyamine and heating at an elevated temperature, preferably at least 150 C., until the halogen groups of the halogeno-acid have been aminated. The hydrogen halide is then eliminated by neutralizing with an alkali such as, for example, sodium hydroxide, potassium hydroxide, ammonia and sodium carbonate. The intermediate salts obtained before neutralization may be added as such to alkaline waters such as boiler waters where they are converted to the free polyamides which are substantially insoluble. In other words, the alkali present in the water functions as a neutralizing agent so that the relatively soluble salt is converted to an insoluble amide. This method is illustrated in the following examples of the preparation of valuable materials, but it is to be understood that it is not wished to be limited by the examples.

Example I A mixture of 13.6 grams (0.04 mol) of N-octadecylchloroacetamide and 2.1 grams (0.02 mol) of diethylenetriamine was stirred 2 hours at 150 to 160 degrees C. The product Was neutralized l I (J lia-1N?!)CHzNCHrCHnIITCHaCHaITTCHafiNC1sHa1 ZNaCl 21120 by adding 2.0 grams of sodium hydroxide in 10 cc. of water.

Example II A mixture of 12 grams (0.033 mol) of N-octadecylchloroacetamide and 2 grams (0.016 mol) of 40% aqueous hydrazine hydrate was stirred for 3 hours at to degrees C., after a brief initial period at a lower temperature to prevent Example III To 0.05 mol of N-octadecylchloroacetamide at 150 to 160 degrees 0., 2.2 grams (0.025 mol) of 68% aqueous ethylenediamine was added dropwise with stirring, and stirring and heating continued 3 hours. The product was neutralized by adding 2.5 grams of sodium hydroxide in 10 cc. of water.

Example IV To 0.05 mol of N-octadecylchloroacetamide at 150 to 160 degrees C., 5 grams (0.025 mol) of piperazine hexahydrate was added with stirring, and the stirring and heating continued for 2 hours. The product was neutralized by adding 2.5 grams of sodium hydroxide in cc. of water.

Example V To 0.05 mol of N-octadecylchloroacetamide at 150 to 160 degrees C. was added 2.7 grams (0.025 mol) of m-phenylenediamine with stirring, and stirring and heating were then continued 2 hours longer. The product was neutralized by adding 2.5 grams of sodium hydroxide in 10 cc. of water.

Example VI To 0.05 mol of N-octadecylchoroacetamide at 150 to 160 degrees C. was added 3.7 grams (0.025 mol) of triethylenetetramine with stirring, and stirring at 150 to 160 degrees C. was then continued 2 hours longer. The product was neutralized by adding 2.5 grams of sodium hydroxide in 10 cc. of water.

Example VII Example VIII To 0.005 mol of N-tetradecylchloroacetamide at 150 to 160 degrees C. was added 0.26 grams (0.0025 mol) of diethylenetriamine, withstirring, and then stirring at 150 to 160 degrees C. was continued 2 hours longer. The product was neutralized by adding .25 gram of sodium hydroxide in 10 cc. of water.

Example IX A mixture of 2.5 grams of beta-chlorobutyric acid and 6.34 grams of octadecylamine (with a mean molecular weight of 264) was stirred 2 hours at 150 to 160 degrees C. Then 1.4 cc. of diethylenetriamine was added and the mixture stirred 3 hours longerat 150 to 160' degrees C. The product was neutralized by adding 1.0 gram of sodium hydroxide in 10 cc. of water.

Example X A mixture of 5 grams of beta-chloropropionyl chloride and 6.7 grams of octadecylamine (with a mean molecular weight of 264) was made at I room temperature, and quickly warmed itseli to a homogeneous liquid mass, which was gradually heated, with stirring, to degrees C. Then 1.4 cc. of diethylenetriamine was added and the mixture stirred 3 hours at 150 to degrees C. The product was neutralized by adding to the resultant mixture 1.7 grams of sodium hydroxide in 10 cc. of water.

Example XI 10.6 grams of octadecylamine (having a mean molecular weight of 264) was added portion-wise to a belt of 10.7 grams of o-iodobenzoyl chloride, and the mixture brought to 150 degrees C. with stirring. Then 2.16 cc. of diethylenetriamine was added and the mixture stirred 2 hours at 150 to 160 degrees C. The product was neutralized by adding to the resultant mixture 1.7 grams of sodium hydroxide in 10 cc. of water.

In a similar manner, other polyamides falling within the general formula may be derived by the reaction of one mol of a halogeno organic acid or acid chloride with one mol of a primary or secondary organic mono-amine followed by reaction of two mols of the resultant product with one mol of an organic polyamine containing primary or secondary amino groups followed by neutralization. For example, by following the teachings of the invention alpha,alpha'-[iminobis (propyleneimino) 1 bis [N-hexadecylacetamidel was prepared from chloroacetyl chloride, N- hexadecylamine and dipropylene triamine-with the elimination and neutralization of hydrogen chloride. Similarly, beta,beta-[iminobis(propyleneimino)] bis(N-lauryl propionylamide) was prepared from beta propionylchloride, normal laurylamine and dipropylenetriamine with the elimination and neutralization of hydrogen chloride.

The term polyalkylene as used herein refers to a radical or group characterized by two or more alkylene groups as in piperazine. The term polyalkylene polyamine refers to a group or radical characterized by at least two aminogroups and by an amino nitrogen atom between two alkylene groups as in diethylene triamine, triethylene tetramine, tetraethylene pentarnine, dipropylene triamine and homologues thereof.
